Introduction: Endoscopy for the screening of esophageal varices (EVs) is costly and cannot be performed in remote areas with limited resources. Recently, certain non-invasive cost effective models have been proposed for the prediction of EVs but have failed recommendation on a larger scale. EVendo score is a recently developed bedside score for the detection of EVs. Therefore, our aim was to determine the utility of EVendo score as a screening tool for the detection of high risk esophageal varices in Pakistani population. Methods: It was a cross sectional study which was conducted in the department of Hepatogastroenterology from January 2021-June 2022.All the patients of either gender aged greater than 18 years with newly diagnosed cirrhosis were included in the study while those patients with prior history of esophageal varices and variceal bleeding as well as those with acute liver failure, renal impairment, non-cirrhotic portal hypertension and those on anticoagulants were excluded from the study. Area under the receiver operating curve (AUROC) was obtained for EVendo score, Aspartate Transaminase to platelet ratio(APRI) and Platelet count to Splenic Diameter and diagnostic accuracy was obtained for these scores in predicting EVs and also in identifying HRVs. Results: A total of 272 patients were enrolled in the study. Among them, 167(61.4%) were males. Most common cause of chronic liver disease was viral hepatitis.On screening endoscopy, EVs were noted in 118(43.4%) patients while high risk EVs (HRV) were noted in 47(17.3%) patients respectively. AUROC was obtained for EVendo score, APRI and Platelet count to Splenic Diameter in predicting EVs and also for identifying HRVs and it was 0.93 (p-value <0.001), 0.821(<0.001) and 0.842(p<0.001) respectively for the prediction of EVs with diagnostic accuracy of 86.76% and 0.852 (p-value <0.001), 0.835(<0.001) and 0.814(p<0.001) respectively for identifying HRVs with a diagnostic accuracy of 84.19%. Conclusion: The performance of EVendo score was reliable and better than the other non-invasive scores in predicting EVs in our population with an excellent sensitivity and diagnostic accuracy in predicting the EVs and also in identifying HRVs. However, studies comprising larger sample sizes are required in this regard.
Introduction: Guidelines recommend periodic endoscopic surveillance for the detection of esophageal varices. However, its avoided by certain patients due to invasiveness and high cost. Identification of noninvasive methods will allow appropriate patient selection. The aim is therefore, to compare the diagnostic performance of different non-invasive indices in predicting esophageal varices. Methods: This was a cross-sectional prospective study which was conducted at the Department of Hepatogastroenterology, Sindh institute of Urology and Transplantation from July 2021 to December 2021.All patients recently diagnosed with liver cirrhosis were included in the study. Upper GI endoscopy was performed in each patient for the detection of esophageal varices. Area under ROC was obtained to determine
Introduction: Most of the lactate in the body is cleared in the liver. Tissue hypoxia results in increased production of lactate and decreased utility of it. Hepatic insult results not only an increase in the blood lactate levels but also is an independent prognostic marker in critically ill cirrhotic patients. Alteration of liver function is indicated by rise in serum bilirubin. The aim of this study was to therefore to assess the utility of blood lactate to Bilirubin index (LBi) in predicting mortality in patients with acute on chronic liver failure (ACLF). Methods: This prospective observational study was conducted from January 2019 to June 2021 at the Department of Hepatogastroenterology, Sindh Institute of Urology and Transplantation. Patients aged > 12 years and presenting ACLF were included and their baseline characteristics were recorded. Primary outcome was observed in terms of 30-days mortality and secondary outcome was six months mortality. These indices were then used to calculate the lactate to bilirubin index (LBi) as [1000 × lactate (mmol/L) × bilirubin (µmol/L)]/2. Area under Receiver operating curves (AUROC) for LBi, Child Turcotte Pugh score(CTP) and Model for End-stage Liver Disease score (MELD) were obtained in predicting both 30 days and six months mortality and at an optimal cutoff sensitivity, specificity and diagnostic accuracy for these scores were calculated. Results: A total number 159 patients with ACLF were included in the study. Most of the patients were young with mean age of 35.1 ±16.8 years. Males were 97(61%). Hepatitis C was the most common cause of chronic liver disease followed by hepatitis B and autoimmune hepatitis seen in 41 (25.8%), 39(24.5%) and 36 (22.6%) respectively. Hepatitis E was the most common cause of acute injury noted in 60 (37.7%) patients. The baseline characteristics showed mean serum lactate levels of 0.93±1.33 mmol/L, bilirubin levels of 258.5 ± 155.3 µmol/L, CTP score of 10.7 ± 1.8 and MELD score of 26 ±7.6. Out of 159 patients, 26 (16.4%) patients died within 30 days due to ACLF related complicaitons while 133 (83.6%) were discharged. AUROC obtained for LBi, CTP score and MELD score in predicting 30-day mortality in ACLF was 0.98, 0.79 and 0.78 respectively. A cut off of ≥11.8 for LBi Index, ≥30 for MELD score and ≥13 for CTP score were significantly associated with increased risk of 30-day mortality in ACLF patients in our population. However, the sensitivity, specificity, PPV, NPV and diagnostic accuracy of LBi in predicting 30-day mortality was significantly higher than that of CTP and MELD score. The diagnostic accuracy of LBi in predicting 30 days mortality was 87.5%. Similarly, AUROC obtained for LBi, CTP score and MELD score in predicting 6-month mortality in ACLF was 0.89, 0.72 and 0.66 respectively and the diagnostic accuracy of LBi dropped down to 76.6% with a sensitivity of 49.28%, specificity of 97.28%, PPV of 94.4% and NPV of 71.54%. Conclusion: Our results showed that LBi score of >11.8 had an excellent sensitivity and specificity in predicting mortality in ACLF with an excellent diagnostic accuracy in predicting one month mortality as compared to the other scores. However, its utility in predicting long term mortality is yet to be proven. Further studies are needed to validate this index.
Niemann pick disease refers to a group of autosomal recessive disorder lysosomal lipid storage disorders with a multisystem involvement with a wide variety of clinical manifestations. The pathogenesis of disease is yet to be defined clearly. Here, we report to you a series of two cases including that of a three-year old girl and a four-year old boy.
Melanosis coli is a condition in which there is blackish to brown discoloration of colon and is commonly associated with chronic anthroquinolone laxative usage. It is frequently diagnosed as an incidental finding on colonoscopy or histopathological evaluation. Here, we present to you a case of a sixty-six years old man with history of constipation and laxative use.
